Abstract:An alternative adsorbent from oil shale semi-coke material for removing chemical pollutants from aqueous solutions was investigated. For this purpose, enriched oil shales with different kerogen contents (57, 79 and 90 wt%) were pyrolyzed in nitrogen atmosphere at 600-900 °C at a heating rate of 10 °C/min and a hold time of 60 min. The surface properties of semicokes, namely Brunauer-Emmett-Teller (BET) surface area, pore volume and pore size distribution (PSD), were determined by nitrogen adsorption. The stu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
